To ch fev/rom it may concern:

.lie it known that l., lowiN E. Banner, citizen of the United States,and resident of Syracuse, in the county of Onondaga and State of NewYork, have invented certain new and useful Improvements in Type-Tits ingMachines, of which the following is a specification.

My invention relates to typewriting inaparticularly to the type bars andhangers therefor, and the object of inyil'ivention is to provide asimple, easyand efficientl type bar bearingby which the type bars areguided against. lateral defiection in the printing l'novenicnts thereofand wherein there is little liability of undue alineinent is provided.

To these and otherends which will hereinafter appear, the inventionconsists in the features of construction, arrangements of parts andcombinations of devices l,hereinafter described`and-more particularlypointed out in the appended claims.

In the accompanyi-nfgg drawil'igs, wherein like referencenumerals'designate like parts in the various views, Figure .l is a frontto rear vertical. sectional View of sufficientnumber of parts of atypewriting .machine to illustrate my invention. Fig. 2 is an enlargeddetail fragmentary sectional view of a type bar and hanger the sectionbeing taken on the line of Fig. 3 and looking' in the direction of thearrow at said line. llig. 3 is a transverse sectional view taken ou theline i/- of Fig. 2, looking in the dirertii-ni of the arrow at said linebut showing` bars. Fig. 4 is au enlarged detail side view of one of thebearing disks. Fig. 5 is an enlarged detail side view of one of the typebar hangers. Fig. (3 is a vertical sectional view taken on the line ofFig'. l, and looking in the direction of the arr'ow at said line; theview illustrating' in .front elevation the type bar segment aud soule ofthe type bars and hangers. the ti- Vpe bars being' shownin section.Fia'. T is a fragmentary front elcvation of au alternativ/.2construction of sog nient and hanger, the type bars being` in section.Fig'. is a detail side sectional elevation ol the Same.

The traine of the machine comprises a hase l.. corner posts-2 and topplate A carriage not shown) is niountfal above the l top plate andcarries a platen ft. Key levers 5 are pivoted in the base of the machineat t3 and are provided with the usual finger keys 7 and restoringlsprings Se levers t) are pivoted at 10 to the key levers and 6o are eachprovided with a slot ll in the lower end portion thereof for thereception of a fixed fulcruni rod l2 which extends beneath the keylevers and'froin side to Side of the machine. The upper end of eachsub-leveris pivoted at i3 to a forwardly extendin.;l link 1+i which hasits forward end pivoted at 15 to a type bar lo.

Each type bar is preferably made of three pieces, a body portion andtwoirnlelieiulent- 7o cheek plates 17 which latter may be stamped out orformed from sheet metal and are located on opposite sides of the bar andse` cured thereto preferably by rivets '18, thusl forming a bifurcatiedportion atthe pivotal end of the type bar i'orreceiving a type barhanger 1S), preferably made of'sheet metal and with smooth or lappedsides. 'By inaking the cheek plates 17 of separate pieccs Iam enabled tosmooth or polish or lap their inner parallel bearing' faces before theyvare attached to the bodior shank of the type bar and so that they will'.zoipcrate with the smooth sides of the hanger with the mini .n'nunamount. of friction, thus conducing to 85 the greatest freedom of actionof the type bar. lf desired, these plaies may be hardened and united tothe type bar by soft rivets` 18. 'l`he hanger l5) has an eye 2t) whichis received within the bifurcated por 9G tion of the type bar, and adish. or collar 2l with a periphera bearingV face. or edge 2t! isseatedin the bearingl of the eve 2t). The disk Qi has its peripheral bearing`sur- ,Y face cut away or apcrtured at. 2l so as toit??? provide openings.or recesses that extend transversely through the dish. When the disk isseated within the eye 2() and the eye is properly positioned Within thebifurcated portion fornuid by the cheek plates lT of inc 10J type liar.rivets 525 ma): be inserted thro 1gb coiimiding.;I openings in therheckplates which register with the openings tl in the bearing dish and theri vets may be upset or headed on the outer faces of therheek plates inor 105 der to' maintain the parts assembled and the .type bar and hangerunited as shown. '.lhe-

rivets are of such diameter that they do not till the openings :'Ltndare situated so that.

they do not contact with the inner bearing iw surface 23` in the eye ofthe hanger. The disk 21 is preferably inade from one-quan ter (1/4) toone-half (1./2)` a thousandth of an inch thicker than the hanger, inorder to prevent the cheek plates'froin pressing unduly. against theside bearings or faces" of the hanger When the rivets are upset orheaded in assembling the parts, thus en l abling the bars to Workfreely. It should be understood, however, that the slight exs cess ofthickness of the bearing kdisk does not preclude the cheek.` plates frombeing set close enough to the sides of the eye of the hanger to preventany lateral shake or inovement of the type bar relatively to its hanger.

By extending the rivets 25 through the apertures 24 in the bearingA diskin the Inanner shown, the rivets interlock with the type bar and bearingdisk and the latter is positively connected to and obliged to turn withthe type bar; the rivets being offset from or arranged on opposite'sides of the center of the bearing `disk or collar and a shearingstrain bein exerted by the rivets on the disk. Furt ermore, it will beseen that the rivets 25 extend through 'the disk at or near.

the peripheral bearing 22 of the disk so that the rivets are enabled toturn the disk with the best possible leverage When the 'type'bar isoperated.

The eye portion of the hanger may be comparatively large and the cheekplates comparatively broad so as to provide suitable side bearings forthe type bar and prevent as inuch as possible lateral shake ordetlection of the bar during its printing` movement; the Wider orbroader these side bearings are made the steadierand truer will thebaroperate, but at the same time these side bearings inust not be solarge as to cause undue friction, and again pressure between the cheekplates and the eye portion of the hanger should be avoided so as not tointerfere with the freely swinging movements of the type bar. .l thecheek plates 'ust contact with the eye portion of the liangei orsubstantially so, without pressing thereupon, the best results areobtainable. Preferably the rivets are headedby a spinning operationinstead of by hammering, so as' to avoid capping the cheek plates andcausiiifr thein to press against the eye portion oi' the hanger and alsocausing them to lose their parallelism, for in practice the innersurfaces of the cheek platesl should be parallel with each other andwith the sides of the hanger, and they, a'sivell as the sides of thehanger, should be smooth and even to get the best results. The disk orbearing :il may be of any suitable diameter and hence -of such size asto provide a coinl'iarativcly large and durable pivotal bearing for thetype bar. l The openings 24 inthe peripheral hearing .of each disk, areslightly larger than the diameter of the rivets contained therein asclearly indicated in Fig. 4, vand constitute recesses which will collectany particles ot dirt or 4metal that niaybecome disengaged from thebearings, thus preventing their working into the close fitting parts andwhich would result in a` cutting ot the bearings and in producing unduefriction he tween the type nar and hanger. 'l`he said recesses may alsoact. as cups to hold -aud supply a lubricant tothe bearing.

It will be seen that lhc construction is such that a closejoint isformed between cach type bar and hanger and that it is ditiiculi' forany dust', grit or rubbings that may drop from the front faceol theplaten to gain access to the pivotal bearings ot? the type bars.

Each hanger is provided with a depemb ing stein 2t) which has a rearbearing edgel 27, and also a. bearing shoulder or edge 2h that extendsat right angles to the bearing edge 27. A forwardly extending,r car 2S)is perforated at 3() for attael'nnent otono end of a coiled restoringspring 3l, the other end of said spring being connected to the 'type harat 32. l

A type bar segment 33 has radial grooves or slots 34 in the front facethereof, and

horizontally disposed grooves or slots l5 are formed in the upper faceot the segment 5 the horizontal :dots alining with 4the slots in thefront face of the segnn'nt. so that the horizontal and radial slots arearranged in pairs, one slot extending al. an angle lo thiother an'd cachpair of slots being adapted lo receive a hanger.

It will be seen that the bottom wall 3o ol each slot. 34 in the fronttace o," the segment is at substantially right angles to the bottom wall37 of thel associated slot in the top olI the segment. 'I`he stem 21' ofeach hanger is received within a radial slot Il-l in the t'roul face ofthe segment and extends sub lantially throughout the length olI saidsloh and the bearing edge 2T ot' the stein titl is seated against thebottom wall lt in thil slol 34 in which tln` hanger is seated. 'l`heparl 2S ol the hanger is received within the alined horizontal slot 35und hears against the bottoni wall il? ol' said horizontal slot.

lt \vill be seen that `by this construction a twisting niovenu-nt ol thehanger around llu` longitudinal axis olf its stem is prevented and thehanger is properly positioned by the walls ot' its l-iorizonlal Islot l,whereas tlul associatwl slot -ll in the l'ront linee oi' the segmentcontains the stein 24' throughout its length and properly positions thchanger in aradial direi-lion and prevents :in v sidowise movement ollllustem ol' the hanger. i\ -set screwtltw is provided foi-each hangerand is received 4within a threayled opening lfl in the froiil face ofthe segment und al a slot 34 therein and said screw bears at its llll'illt) . the hanger would come at tit) assess rear end against theinclined edge a0 of its associated'hanger and secures it in position inthe slotted segment and together with the Walls of the slot prevents anymovement of the hanger in any direction. By providing' slots in thesegment at right angles to each other and providing cooperating portionson the hangers which yare seated in said slots and extend at rightangles to each other, the hangers are properly positioned and guidedagainst lateral movement or twisting in any direction, and an accuratepositioning of the hangers may be secured and maintained.

VIt has been found in practice that without the slots there is atendency for the hanger to twist-or move out of proper radial positionwhen the. set screw is driven home, provided there be the slightestlooseness or play between the hanger and the sides of the radial slotl3st-, and provided also the axis of the screw does `not enter orregister accurately with the longitudinal center line of the hanger andwhich would enable the screw to force the hanger sidewise or twist it insuch manner that the rear edge 27 of an angleto the rear wall of theslot 34, whereas it' should be parallel and in contact for the fulllength of the stein or shank ot the hanger. lt will be understood, ofcourse, that if the hanger be thus twisted or turned aside from the trueposition the type end otl the type bar will bey thrown out oi' properradial position and the type will not print in alinement. l'iut byproviding the slots 35 in the segment and seating the shoulders 28therein, the screws are unabletotwist the hangers or move them ont ofproper radial position.

That portion ot' thc segnicnt wherein the tapped holes -fi lorthe screwsare provided is niade or torined in the nature of a forwardly projectingflange Sii-i, while the body orfircb portion 243i ol thisl segment .isarranged in rear ot said lial'lge portion Z'il lleretoforc thtl radialslots for receiving' the hangers ha\e heen inadc only in the said flangeportion ihr and these were i'ound to bc insnliicicnt to maintain thchangers prop orly in their radial positions when the reA tainingl screwswere tightened up.

it will bc observed that l have provided not only the horizontal slotsor grooves 35 but that l have also cut, the radial grooves -t entirelybeyond the flange and into the body or web olI thc scgnient, and at thesame time l hare made these grooves in the body or web portion longerthan the grooves in the flangiportion and have ilicreascd the lengthso'tI thtl hangt-rs correspondingly, this' increased length ol' bothgrooves and hangl ers reducing"liability o'lA twisting' or lateralmotion ot the hangers to the minimum.

The radial groovcswhich extend through andwbcyond the tlangc into thebody or web Of the segincnt have been designated of the segment.

at right angles to each other,

V type ha r and unite the rotation between said disk and for thereception of the hangers constituteone set of grooves and the grooves inthe web or body constitute another set of grooves. The last mentionedset oflgrooves are represented in Fig. 6 by the reference ttl,

The grooves 35 are n the same radial planes as the grooves 34 althoughthey are cut at'right anglesto the latter and parallel with the axis ofthe internal cylindrical face In Figs. 7 and 8 have shown a preferredform of construction embodying my invention. ,ln these figures I haveillustrated a hanger 19, similar to that previously described exceptthat said hanger is provided with a shoulder atl that extends at'anangle to the bottom Walls of both slots v34 and in which the hanger isreceived, and .a set screw 38a is disposed in an inclined position andis received within a threaded opening 39 in the segment Aand bears atits'inner end against the shon'lfder 4l on the hanger. A pressureexerted by. the screw 38a on its 'hanger will force it lboth downwardlyand rearwardly until both bearing faces of the hanger, which are at lright angles to' each other, are firmly seated against the bottom walls36 and 37 of their slots, which are also thus firmly seating andsecuring the type bar hanger in place. c v
